TECHNICAL FIELD

The present invention relates to a mobile telephone terminal device, commonly named as mobile phone. More specifically, the present invention relates to a terminal device of slender rod-formed pen-like mobile telephone, referred to as pen-type mobile telephone for short.

BACKGROUND TECHNOLOGY

In recent years, along with the development of mobile telecommunication technology, mobile telephone is increasingly popularized. The user's demand on the terminal of mobile telephone, namely the mobile telephone, is increasingly higher. Its main point is to demand the design of mobile telephone to develop in the direction of miniaturization. Thus, lighter, thinner and smaller is the target pursued by mobile telephone manufacturers. Therefore, various miniature mobile telephones increasingly come out in succession.

For the direct-holding type mobile telephone, if the length of mobile telephone is too short, it will result in unclear transmitted voice. And the width of display screen can not be make too narrow due to the horizontal arrangement. Both length and width are subject to certain limitation. Thus it is difficult to design a further smaller direct-holding type mobile telephone. At present, the minimum size for the direct-holding type mobile telephone is about 90 mm×45 mm×18 mm.

In order to make mobile telephone exquisite with the earphone and microphone of mobile telephone being within the suitable relation of proportion, the flip-type miniature mobile telephone is invented. However, although the flip type mobile telephone reduces the length, but meanwhile it increases the thickness of mobile telephone. Moreover, the structure of flip type mobile telephone is too complex, and it puts higher requirements on the use performance and reliability. Thus the cost is higher, thus it is expensive. At present, the minimum flip type mobile telephone is 78 mm×42 mm×20 mm.

At the present technical level, it is almost impossible to make mobile telephone smaller. It is an affair daring not to think of making mobile telephone with size similar to that of a pen. Because it is necessary for mobile telephone not only to install display, control button, control key, digit and function key, telephone receiver, and earphone etc., but also to install lot of mobile telephone's wafer and its affiliated circuit, SIM card, cell and other auxiliary elements and parts. In accordance with the conventional circuit design and on the basis of the traditional way of thinking, it is impossible to make mobile telephone smaller.

To sum up, there exist the following shortcomings for the existing miniature mobile telephone:

1. Due to present design in wafer of mobile telephone and the scale of its affiliated circuit, it is impossible for the area of internal circuit to be made smaller.

2. As the digital display of mobile telephone is in horizontal arrangement, at least an 11-bit digit should be arranged for one line. Thus the width of display screen can not be made too narrow. Therefore the width of mobile telephone should be correspondingly wider, limiting the contour of mobile telephone to develop in the direction of being narrower.

3. For traditional mobile telephone, setting SIM locking socket in housing for the installation of SIM leads to the difficulty for conventional mobile telephone to reduce thickness.

4. Moreover external cell is installed at said SIM locking socket to cover this SIM card, and external cell itself must possess plastic housing, therefore, the thickness of conventional mobile telephone further increases.

5. As the digit key of mobile telephone is in horizontal arrangement, therefore mobile telephone can only be operated in vertical direction. The operation mode is single, and sometimes the use is not convenient. Above-mentioned various problems limit mobile telephone to develop in the direction of being in slender form.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, it is shown the front elevation view for contour of a pen type mobile telephone according to an embodiment of the present invention. It can be seen from the figure that a pen type mobile telephone in accordance with the invention includes housing 1, display 2, button 3, operating key 4, digit and function key 5, telephone receiver 6, and earphone 7, which are needed by terminal of mobile telephone. What is different with terminal of conventional mobile telephone is that the pen type mobile telephone possesses slender rod-form and small volume; easy to insert into pocket. In accordance with the embodiment, concrete size of housing 1 is: length 140 mm×width 35 mm×thickness 23 mm; Ratio between length and width is more than 4:1. In addition, hang buckle 10 is installed at its top and back (refer to FIG. 2), so as to be convenient to hang in pocket, convenient for carrying like a pen.

Referring to FIG. 2, a socket 9 inserted with drawer-type SIM card plug & receptacle is set at the side face of pen-type mobile telephone of the invention. Detailed explanation will be given for drawer-type SIM card plug & receptacle in the following in combination with FIG. 3. In accordance with a kind of expansion for the invention, a laser exit 8 is set at the bottom of the pen-type mobile telephone.

In order to realize the slender rod-formed pen-type mobile telephone, display 2 of the invention is slender and in longitudinal setting, namely the long side is in up and down direction, and the wide side is in left and right direction. Length of the display is 40˜60 mm, while the wide side is 22˜32 mm.

In addition, it is allowed to make oblique arrangement for said digit and function key 5, with angle of inclination between 30°˜60, so as to arrange these digit and function keys 5 in the narrow & long area. Moreover, when the user dials, it can be used for operation both in vertical direction and horizontal direction, giving the user convenience.

In addition, the more important is that various function parts in terminal of mobile telephone should be installed in the slender rod-formed housing 1. Moreover it is necessary not only to bring into normal play the functions of various parts, but also to ensure the quality of call and convenience of use for the entire device. In the following, internal structure of the pen-type mobile telephone of the invention will be explained in combination with FIG. 3 and FIG. 4.

FIG. 3 shows internal structure of pen-type mobile telephone for the invention. In concrete terms, it shows structure layout of various parts in front cover 1A.

In reference to FIG. 3, in accordance with internal structure of pen-type mobile telephone for the invention, it mainly includes: printed circuit board 11, radio frequency module 12, fundamental frequency module 13, SIM card plug & receptacle 14. In order to make circuit more compact, fine and close, the printed circuit board in the invention uses more than 6 layer printed circuit board, for example 7 layer or 8 layer, even 9˜10 layer printed circuit board. Width of the printed circuit board is smaller than the width of the housing 1, namely front cover 1A. The circuit part is mainly divided into radio frequency module 12 and fundamental frequency module 13. The widths of both modules must be less than 35 mm.

Through internal use of more than 6 layer printed circuit board, designing the main circuit part into radio frequency module and fundamental frequency module with their width less than the width of the slender and long housing in accordance with the above-mentioned novel structure layout, the basic aim of the invention is achieved, namely based on the pen-type mobile telephone of the invention, it is possible to make its width less than 35 mm, even less than 25 mm.

In order to make the thickness of pen-type mobile telephone for the invention smaller, less than 23 mm, the invention especially uses a novel drawer-type plug & receptacle 14. It is mainly composed of a drawer-type locking socket 14A and a card fixing device, with a size less than 30 mm for length and less than 20 mm for width. The concrete structure and detailed explanation about this kind of drawer-type SIM card plug & receptacle will not be given here and reference is directed to the not yet published patent application No. 02269510.9 applied for by the applicant. The emphasis here is given to its manner of the insertion connection. As the patterns of drawer-type side-insertion or direct insertion and flatwise placement are used to place and fix the SIM card, the body of pen-type mobile telephone in accordance with the invention can be made narrower, namely the thickness is smaller. This is because this kind of inserting and drawing-out of the SIM card from side like operating a drawer can avoid the increase of body thickness resulting from setting and installation of SIM locking socket in the housing, and therefore it is allowed to install cell inside the housing 1. Thus it is allowed to further reduce the thickness of the pen-type mobile telephone. But traditional mobile telephone must use external cell, because in installing or dismantling the SIM card, it is necessary to dismantle external cell that covers the SIM card. External cell itself must have plastic housing, thus it cannot but increase the thickness of the mobile telephone.

In order to further reduce the thickness of a pen-type mobile telephone of the present invention, a pen-type mobile telephone of the present invention in accordance with an embodiment uses a built-in cell 19 (refer to FIG. 4). Because the built-in cell 19 does not need above-mentioned necessary plastic housing as an external cell does, the pen-type mobile telephone of the invention can make its thickness very small, for example less than 20 mm.

In accordance with the above-mentioned pen-type mobile telephone, said housing (1) can be made less than: length 140 mm×width 25 mm×thickness 18 mm.

In reference to FIG. 4, the pen-type mobile telephone in accordance with the invention includes also built-in antenna 17, buzzer 18 in back cover 1B. In the figure, reference sign 20 indicates a screw hole for installation. It is also the sole screw hole for installation in the embodiment. Installation of the back cover 1B and front cover 1A depends mainly on coordination between several locking sockets 21 and several card catches 22 at front cover 1A to have close combination, and meanwhile through installation of screw in screw hole 20 to reach the purpose of firmness.

In reference to FIG. 3 again, the pen-type mobile telephone in accordance with the invention sets a function expansion area at the bottom of slender printed circuit board 11. In order to realize the functions of earphone, charging and data interface etc., a multiple-in-one socket 16 is installed in function expansion area of the pen-type mobile telephone of the invention, and it is a three-in-one socket in the embodiment. In addition, in the function expansion area 15, it is allowed to install vibrating motor 23 for “calling number display” and/or a laser for a laser pen.
